This is a parallel life he maintained meticulous in recent years. Former classmates and colleagues described him as a mediocre quality and is easy to forget,, probably innate, that he cultivated - conscious, he would say -. "Martyrdom operations" to cover the dedication to what he calls Over the years, Mr. Breivik, who is 32, participated in the debate on internet forums about the dangers of Islam and immigration. It is unclear at what point he decided that violence is the solution to the ills that he believed European civilization was ripped apart. Before the attacks that he has recognized mounting on government buildings and summer camp kids on a Friday, he was careful not to telegraph his intentions. "He did not say anything you can remember," said Stig Fjellskaalnes, who knew Mr. Breivik when he was a member of the conservative Progress Party of Norway in early 2000. "He's one of the crowd, if you know what I mean. You forget it." But it's about a decade ago that Mr. Breivik began to change. After a schoolboy who likes hip-hop and have a Muslim friend, in his 20s he began to see the free flow of immigrants to Norway and elsewhere in Europe as the enemy, and they are trying to accommodate them as traitors, only worthy of execution. "Around 2000 I realized that the struggle of democracy against the Islamization of Europe, European multiculturalism, lost," he wrote in a manifesto that he published on the Web shortly before the attack. "I decided to explore alternative forms of opposition. Protest saying that you do not agree. Resistance to say you will stop this. I decided I wanted to join the resistance movement." With a 1,500-page manifesto, which he said took three years to complete, Mr Breivik trying to find common cause with the xenophobic right-wing groups around the world, especially in the United States. He quoted extensively from the writings of Islamic anti-American bloggers, and cutting and pasting whole sections of the manifesto written by Theodore J. Kaczynski, known as the Unabomber, to themselves, replacing "left" with "multiculturalism" as the object of calumny. "He has an apocalyptic view," said Magnus Ranstorp, research director of the Center for Asymmetric Threat and Terrorism Studies at the Swedish National Defense College. "He thought it would take 70 to 80 years to reverse the" Arabization "of Europe. He sees himself as part of history." Early life, Mr. Breivik, far from being radical, it seems to be on track to join the Norwegian political establishment. He grew up in Skoyen, a middle-class district west of Oslo. His father, a civil servant, and his mother, a nurse, divorced when she was 1. In addition, his childhood seems to have smoothly; Mr. Breivik said in the manifesto that was happy. He attended an elite high school where the country's current king, Harald V, and his son had studied. Former classmates remember him as quiet but smart, with a little rebellious streak: he is a prolific graffiti artist. Towards the end of high school, he joined the youth wing Progress Party, pulled anti-immigrant platform and bent the capitalist market. But those who knew him from those days said that he failed to leave much trace. He began to struggle with life, those who knew him said. He became estranged from his father, who moved to France. Then her sister, Elisabeth, to whom he seemed to rely in the absence of his father, moved to the United States and married an American. "Elisabeth is the only stone in life," said a former childhood friend, who would not give his name for fear of retaliation because she was not ethnic Norwegian. "When Elisabeth left, it really affected him. I think that's when Anders started to spiral." This is the time when, according to his manifesto, his political views began to change. He began to see what he says was hostility from the Muslim youth. He was attached to the reports of attacks against people of ethnic Norwegian and ethnic Norwegian women rape by immigrant groups.
